CAR-COUPLING.

SPECIFICATION formingpart of Letters Patent No. 257,659, dated May 9, 1882. Application filed November 28, 1881. (No model.)

My invention has reference to that class of' I o automatic car-couplers which are so constructed that cars provided with them can be coupled to Others having the ordinary link-and-pin arrangement, and maybe thus described: The draw-head in outward appearance resembles 1 those of ordinary construction; but instead .of the usual rectangular chamber following the outline of the outside, the chamber formed in the draw-head in my invention is oval in sec- 'tion, and has formed in its front the opening to receive the link, the mouth being flared from this in every direction and the chamber flared onthelineot'thelinkfromitsrearend. Within this chamber is contained a ball ofv cast metal somewhat less in diameter than the internal width of the link. This may be cast loose in the chamber, or the draw-head so constructed that it may be inserted. The normal position or seat of this ball in the chamber is just below and in rear of the opening through which 0 the link enters, in which place it will lie within the link and retain it in position when the cars are coupled. To lift this ball and allow the link to bedrawn out when the cars are to be uncoupled Iad optthe followingdevice: I place 5 in a slot formed in the under side of the drawhea-d an arm mounted rigidly on. a pivot pin or spindle, which passes through the drawhead and is carried out at one side. By turning this pivot and raising the arm, for which 40 suitable means are provided, the ball is thrown up into an inner recess formed in therear and upper part of the chamber, and the link so released therefrom may be drawn out. For full comprehension, however, of the invention, reference must be had to the annexed drawings, in which-- Figure 1 is a longitudinalvertical sectional elevation of my invention; Fig. 2, a top view, partly broken away; Fig. 3, a bottom view, looking up; Fig. 4, a side view; and Fig. 5, a

transverse vertical sectional elevation on line :20 m, Fig. 1.

A is the draw-head, A being the internal chamber of the section shown in Figs. 1, 2, and 5, and A the mouth through which the link B enters. This month A is, as shown in Figs. 1 and 2, made flaring, so that the link can be introduced at almost any angle, thus allowing cars of difl'erent heights to be coupled together. The flaring outline of the back of the chamber A, on the plane in which the link lies, also facilitates its entry.

O is a ball, of cast metal, which, when the link B has been introduced into the chamber A and the cars coupled together, lies in the position shown in Fig. 1, within the link, and keeps it in place.

A is a slot formed in the under side of A, and D a pivot pin or spindle passing through the draw-head and on either or both sides beyond it, and E isan arm, the upper surface of which may correspond with the outline of the chamber 'A at that point. This is mounted rigidly on the spindle D, and when not in use is generally ElllOW'd to hang down, as shown in Fig. 1, thus leaving the slot A open and allowing any dirt to fall through it.

D is a crank mounted on the spindle D, from which a cord or rod may be taken to the top of the car for raising said crank and turning the spindle D.

F is a rod'termiuating in a fork, F, with slotted sides pivoted to the end of D, so as to form a universal joint therewith], and fur-'85 nishetl at itsouter end with asuitable handle or ring. This rod is of length sufficient to project slightly beyond the side of the ear, and

has a suitable rest provided for it.
